Southern Ocean could slow global warming
12-05-2006 · EurekAlert!A new climate model predicts that the Southern Hemisphere Westerly Winds' shift poleward will store carbon dioxide and heat in the deep ocean. Although atmospheric warming will slow, sea level will rise faster.

04-25-2007 · EurekAlert!
As the national repository for geological material from the Southern Ocean, the Antarctic Marine Geology Research Facility at Florida State University in Tallahassee, Fla., houses the premier collection of Antarctic sediment cores -- and a hot new acquisition will offer an international team of scientists meeting there May 1-4 its best look yet at the impact of global warming on oceans worldwide.

- Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
02-05-2008 · EurekAlert!
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of surface waters. This is a result from an Antarctic expedition led by the Alfred Wegener Institute, part of the Helmholtz Association. On Feb. 5, scientists will discuss pressing questions of Antarctic research aboard the icebreaker Polarstern in Cape Town. Federal research minister Dr. Annette Schavan will use the opportunity to meet scientists and South African ministerial colleagues.

- Pacific Northwest hypoxic events unprecedented
02-14-2008 · EurekAlert!
A review of all available ocean data records concludes that the low-oxygen events which have plagued the Pacific Northwest coast since 2002 are unprecedented in the five decades prior to that, and may well be linked to the stronger, persistent winds that are expected to occur with global warming.

- Smithsonian scientists report new carbon dioxide study
03-12-2007 · EurekAlert!
Researchers at the Smithsonian Environmental Research Center report that doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. This response suggests a limited capacity of Earth's ecosystems to stabilize atmospheric CO2 and slow global warming. These findings add a new perspective and a measure of caution suggesting that elevated CO2, by altering microbial communities, may turn a potential carbon sink into a carbon source.

- Corals and climate change
08-22-2007 · EurekAlert!
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals. Fully operational this month, this new lab has begun to study how corals respond to the combined stress of greenhouse warming and ocean acidification. The lab is the first to maintain corals under precisely controlled temperature and carbon dioxide conditions while exposing them to natural light conditions.

- New research may lead to better climate models for global warming, El Niсo
12-07-2007 · EurekAlert!
From nine different countries, 150 scientists are starting a program to gain insights about the Earth's climate and the complex system involving the oceans, atmosphere and land. They are studying the Southeastern Pacific Ocean off South America's west coast -- research that should improve global computer climate models, which would lead to improved predictions about global warming and El Niсos, said C. Roberto Mechoso, UCLA professor of atmospheric and oceanic sciences, who chairs the program.
